Blob	(	const char *	data,
		std::size_t	len
	)

Construct a Blob with data of a given length

Constructs a Blob using a default implementation using new/delete to manage the blob-data and the shared data object. The first len bytes of the data pointed to by data are copied to this Blob.

void assign	(	const char *	data,
		std::size_t	len
	)

assigns the data to this blob object

char* reserve	(	std::size_t	len,
		bool	shrink = false
	)

makes sure, the buffer it at least len bytes. If shrink is set, the buffer will be exactly len bytes. Data is not preserved when reallocated.

const char* data

(

)

const

Returns a pointer to the data or 0 if no data is set.

std::size_t size

(

)

const

Returns the size of the data
